37° Flared JIC Fittings — 316 Stainless Steel

About JIC Male and Female Connectors

A JIC connector is the basic transition between a 37° flared tube and a threaded port. The male connector has an external thread that screws into a pump, valve, cylinder or manifold port, with a 37° flare nose on the other end for the tube nut. The female connector reverses this, carrying an internal thread so it can accept a male pipe-threaded component such as a gauge, nipple or valve stem.

The flare end seals metal to metal on the 37° cone, so the sealing method on the threaded side is what usually drives selection. Tapered NPT and BSPT threads seal on the thread flanks and need a suitable sealant or tape. Parallel BSPP, SAE/MS straight and metric threads do not seal on the flanks; they rely on a bonded seal, O-ring or face seal at the port.

These SS316 connectors are offered across NPT, BSPT, BSPP, SAE/MS and metric threads, which makes them practical for mixed-standard equipment where a US-built pump feeds a European manifold, or for retrofit work on older hydraulic skids. Typical uses include hydraulics, oil and gas and heavy equipment.

• Male connector for a threaded port; female connector to receive a male-threaded component.
• Identify the port thread first (tapered or parallel), then the tube OD for the flare end.
• Filter the table by thread type and size, then request a quote from Valvenok.
